下面就一般習慣分類介紹幾種開關電源：

1、AC/DC電源

該(gai)類(lei)電源(yuan)(yuan)也(ye)稱一(yi)次電源(yuan)(yuan)——AC是交流(liu)(liu)，DC是直流(liu)(liu)，它自電網取得能量(liang)，經過(guo)高(gao)壓(ya)(ya)整流(liu)(liu)濾波得到一(yi)個直流(liu)(liu)高(gao)壓(ya)(ya)，供(gong)DC/DC變換(huan)器在輸(shu)出端獲得一(yi)個或幾個穩定(ding)的(de)直流(liu)(liu)電壓(ya)(ya)，功(gong)率(lv)從幾瓦(wa)－幾千瓦(wa)均有產品(pin)，用于不同場(chang)合。屬此類(lei)產品(pin)的(de)規格型號繁(fan)多，據用戶需要而定(ding)通(tong)信(xin)電源(yuan)(yuan)中的(de)一(yi)次電源(yuan)(yuan)（AC220輸(shu)入，DC48V或24V輸(shu)出)也(ye)屬此類(lei).

2、DC/DC電源

在通信(xin)系(xi)統中(zhong)也稱二次(ci)電(dian)(dian)源，它是由一次(ci)電(dian)(dian)源或(huo)直(zhi)流(liu)電(dian)(dian)池組提供(gong)一個(ge)(ge)直(zhi)流(liu)輸(shu)入(ru)電(dian)(dian)壓，經DC/DC變換以后在輸(shu)出端獲一個(ge)(ge)或(huo)幾(ji)個(ge)(ge)直(zhi)流(liu)電(dian)(dian)壓。

3、通信電源

通信電(dian)(dian)(dian)(dian)(dian)源(yuan)其實質上(shang)就是DC/DC變換器式(shi)電(dian)(dian)(dian)(dian)(dian)源(yuan)，只是它(ta)一(yi)般(ban)以(yi)直流(liu)－48V或－24V供電(dian)(dian)(dian)(dian)(dian)，并用后備電(dian)(dian)(dian)(dian)(dian)池作(zuo)DC供電(dian)(dian)(dian)(dian)(dian)的備份，將DC的供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)變換成電(dian)(dian)(dian)(dian)(dian)路的工作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)，一(yi)般(ban)它(ta)又(you)分(fen)(fen)**供電(dian)(dian)(dian)(dian)(dian)、分(fen)(fen)層供電(dian)(dian)(dian)(dian)(dian)和(he)單板供電(dian)(dian)(dian)(dian)(dian)三種(zhong)，以(yi)后者可靠(kao)性較高。天津直流(liu)穩壓(ya)穩流(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)生產廠家奧凱(kai)電(dian)(dian)(dian)(dian)(dian)氣熱忱歡迎(ying)新(xin)老客戶惠顧。

如何(he)和減(jian)少高頻開關電源紋波(bo)的產生

高頻(pin)開(kai)(kai)關(guan)電源(yuan)經常會出現紋(wen)(wen)波(bo)(bo)，這(zhe)是讓人比較煩惱和的(de)一件(jian)事，想要(yao)和減少紋(wen)(wen)波(bo)(bo)就要(yao)先找到(dao)高頻(pin)開(kai)(kai)關(guan)電源(yuan)紋(wen)(wen)波(bo)(bo)的(de)種類和產生的(de)原因，下面奧(ao)凱(kai)電氣廠家為你(ni)講(jiang)解高頻(pin)開(kai)(kai)關(guan)電源(yuan)紋(wen)(wen)波(bo)(bo)的(de)和減少方(fang)法。

基本要求：使用示波器AC耦合 ，20MHz帶寬限制 ，拔掉探頭的地線

1，AC耦合是(shi)去(qu)掉疊加(jia)的直流(liu)電(dian)壓，得到(dao)準確的波形。

2，打(da)開20MHz帶寬(kuan)限制是防止(zhi)高頻噪聲的(de)干擾，防止(zhi)測出錯誤的(de)結果。因為高頻成分(fen)幅值較大，測量(liang)的(de)時(shi)候應除去。

3，拔掉(diao)示波器探頭的(de)(de)接地(di)夾，使用接地(di)環(huan)測(ce)量(liang)，是為了減少干擾(rao)。很多部門沒有接地(di)環(huan)，如果誤差允許也直接用探頭的(de)(de)接地(di)夾測(ce)量(liang)。但(dan)在(zai)判斷是否合格時要考慮這(zhe)個因素。

還有一點是(shi)要使(shi)(shi)用50Ω終(zhong)端。橫河示(shi)波(bo)器的資料上介紹(shao)說，50Ω模(mo)塊是(shi)除(chu)去DC成分，準確測量AC成分。但是(shi)很少有示(shi)波(bo)器配這種專門的探頭，大多數情況是(shi)使(shi)(shi)用標配100KΩ到10MΩ的探頭測量，影響暫時不清楚(chu)。

上面是測量(liang)開關紋波時基(ji)本的注意事項(xiang)。如果示波器探(tan)頭不是直接接觸輸出(chu)點(dian)，應該用雙絞(jiao)線(xian)，或者50Ω同(tong)軸電(dian)纜方式測量(liang)。

在測(ce)量高頻噪聲時，使(shi)用(yong)示(shi)波器的(de)全通帶，一般(ban)為幾百兆到GHz級(ji)別。

新型組(zu)合(he)式(shi)電(dian)(dian)源(yuan)IC：升壓(ya)(ya)(ya)(ya)式(shi)DC/DC 變換(huan)器的(de)(de)效(xiao)率(lv)高但紋波及(ji)噪聲(sheng)(sheng)電(dian)(dian)壓(ya)(ya)(ya)(ya)較(jiao)大(da)，低壓(ya)(ya)(ya)(ya)差(cha)線性穩壓(ya)(ya)(ya)(ya)器效(xiao)率(lv)低但噪聲(sheng)(sheng)**小，這(zhe)兩者結合(he)組(zu)成的(de)(de)雙(shuang)輸(shu)(shu)出電(dian)(dian)源(yuan)IC 可(ke)(ke)較(jiao)好(hao)地(di)解(jie)決效(xiao)率(lv)及(ji)噪聲(sheng)(sheng)的(de)(de)問題。例如(ru)，數字電(dian)(dian)路部分(fen)采(cai)用升壓(ya)(ya)(ya)(ya)式(shi)DC/DC 變換(huan)器電(dian)(dian)源(yuan)而對噪聲(sheng)(sheng)敏感的(de)(de)電(dian)(dian)路采(cai)用LDO 電(dian)(dian)源(yuan)。這(zhe)種(zhong)電(dian)(dian)源(yuan)IC 有MAX710/711，MAX1705/1706 等(deng)。另一種(zhong)例子是電(dian)(dian)荷泵+LDO 組(zu)成，輸(shu)(shu)出穩壓(ya)(ya)(ya)(ya)的(de)(de)電(dian)(dian)荷泵電(dian)(dian)源(yuan)IC，例如(ru)MAX868，它可(ke)(ke)輸(shu)(shu)出0～-2VIN 可(ke)(ke)調的(de)(de)穩定(ding)電(dian)(dian)壓(ya)(ya)(ya)(ya)，并可(ke)(ke)提供(gong)30mA 電(dian)(dian)流(liu)；MAX1673穩壓(ya)(ya)(ya)(ya)型電(dian)(dian)荷泵電(dian)(dian)源(yuan)IC 輸(shu)(shu)出與VIN 相同的(de)(de)負壓(ya)(ya)(ya)(ya)，輸(shu)(shu)出電(dian)(dian)流(liu)可(ke)(ke)達125mA。奧凱電(dian)(dian)氣(qi)以(yi)快的(de)(de)速度提供(gong)前(qian)列的(de)(de)產品質(zhi)量和好(hao)的(de)(de)價格及(ji)完(wan)善的(de)(de)售后服(fu)務。
